Description

The utility model relates to electrical engineering and can be used to accommodate electronic equipment of a modular type.

The closest analogue adopted for the prototype is the housing for placement of microprocessor functional modules of the DEP depRTU company (Source of fame: http://dep.ru/upload/iblock/f27/f27d9eeb97aa3a65a3d20fla6cd76351.pdf).

The well-known analogue adopted for the prototype is made of metal for protection against interference and for its intended purpose, to accommodate microprocessor functional modules. A case containing guides for placement of microprocessor functional modules consists of several parts made in the form of the nth number of panels interconnected by means of fastening. The front panel of the case is formed of several panels, each of which is designed to fix a separate microprocessor functional module, and their number depends on the number of microprocessor functional modules. Each panel with a separate microprocessor functional module is attached to the case by means of fastening. In addition, the side walls of the housing are made with stiffeners, and the upper panel that performs the function of the cover is made with perforation. The prototype has a complex construction of parts.

The disadvantage of the prototype is the complex design of the housing and its parts (see Fig. 1), containing many parts: panels, fasteners, guides, the front panel is made integral.

- the case is assembled from separate panels: the base, side walls, cover and back wall using a variety of screws, while the front panel of the case consists of n number of panels;

- to insert each microprocessor functional module into the case, you first need to fix the guides in the case, then fasten each microprocessor functional module to a separate panel, and then fix each panel with the module to the case with screws;

- the housing cover is made with perforation (numerous ventilation holes).

These arguments significantly increase the complexity of the assembly, as the case itself, and the entire modular electronic device.

The technical result of the claimed utility model is to simplify the design of the housing, which reduces the complexity of manufacturing the housing and the assembly of the device as a whole.

The technical result of the claimed utility model is achieved by the fact that in the housing for accommodating microprocessor functional modules made of parts, both parts of the housing are bent, while the first part of the housing is bent U-shaped, forming side walls and the front, which is the front panel of the housing, made with holes intended for microprocessor functional modules, and the side walls in the upper and lower parts are made with bends inward; the second part of the body includes upper, lower, end and side walls, while the upper and lower walls of the second part of the body are made with U-shaped protrusions and bends inwardly bent, on which there are slots; and the side walls of the second part of the housing contain locking elements for connecting the first part of the housing with the second. Fixing elements for connecting the first part of the housing with the second are made in the form of protrusions with a bend. Both parts of the body are made of metal.

The essence of the claimed utility model is presented in the figures.

In FIG. 1 shows a prototype housing; FIG. 2 is a general view of the inventive housing of the device, and in FIG. 3 and 4 show: a general view of the first and second parts of the housing, respectively, in FIG. 5 shows the assembly sequence, where the following notation:

12 - bends, bent inward, on the upper and lower walls of the second part of the body;

13 - slots on the bends, bent inward, on the upper and lower walls of the second part of the body;

14 - U-shaped protrusions on the upper and lower walls of the second part of the housing;

15 - fixing elements in the form of protrusions with a fold on the side walls of the second part of the housing;

16 - microprocessor functional module;

17 - backplane;

18 - fastening means.

The inventive utility model is a housing for placement of microprocessor-based functional modules made of parts 1 and 2. Parts of the housing 1 and 2 are bent, while the first part of the housing 1 is bent U-shaped to form the front 3 and side walls 4. The front wall 3 is a front panel the housing, made with holes 5, designed for microprocessor functional modules. The side walls 4 in the upper and lower parts are made with bends 6, bent inward. The second part of the housing 2 includes upper 9, lower 10, end 8 and side walls 11, while the upper 9 and lower walls 10 of the second part of the housing are made with U-shaped protrusions 14, designed to fix the microprocessor functional modules vertically, bent inwards bends 12 which have slots 13 for inserting microprocessor functional modules. The side walls 11 of the second part of the housing 2 contain locking elements 15 for connecting the first part 1 of the housing with the second 2. The locking elements 15 for connecting the first part of the housing 1 with the second 2 are made in the form of bends with bends. Both parts of the housing 1 and 2 are made of metal. The number of holes 5 on the front wall of the 3 - front panel of the housing is equal to the number of microprocessor functional modules 16.

The assembly of the inventive device is shown in FIG. 4 and proceeds as follows. Each microprocessor functional module 16 is sequentially inserted into the slot 13 of the second part of the housing 2, then all microprocessor functional modules 16 are connected to the backplane 17 mounted on the end wall 8 of the second part of the housing. U-shaped protrusions 14 on the upper and lower walls of the second part of the housing 2 fix the microprocessor functional modules 16 vertically, helping to align them with the backplane 17. After installing all the microprocessor functional modules 16, the first part of the housing 1 is connected to the second part of the housing 2 by snap , while the holes 7 in the first part of the housing and in the second part of the housing are combined and fixed by means of fastening 18.

The prototype case is made of many separate panels and is assembled using screws, in the claimed case there are only two parts made bent, while in one of the parts of the case the front wall is a front panel in which openings for microprocessor functional modules are made, and in the prototype front the panel consists of N number of parts equal to the number of modules, each of which is attached to the housing from above and below by screws; side panels are made with stiffeners and on top and bottom with grooves. In the prototype, for inserting each microprocessor functional module into the case, it is first necessary to fix it to a separate panel that is bent, and to fix the guides for each module in the case, and then additionally fix the fastening elements to the upper and lower panels of the case. In the claimed case, in both parts of it, slots are made on the bends, which serve as guides for each module and do not require additional rails to be installed in the case like in the prototype, and also do not require fasteners for fixing the equipment inside the case. Fasteners in the inventive case are used (there are 4 in total as shown in figure 4) for fixing two parts of the case. Thanks to this, the assembly process of the device and the insertion time into the module housing is much reduced. The housing cover is made with perforation (numerous ventilation holes), in the inventive housing, the upper wall is made blind, without holes.

Thus, taking into account the above, we can conclude that, unlike the prototype, the claimed housing design is much easier to manufacture and the assembly process of the entire device is much faster.
